Corrected entry: When the Munro's pick up Cassie's friend Gretchen, the crew can be seen reflected in the side of the car. They are also visible when they drop her off. (00:03:20)
Corrected entry: When the two families are eating together outside around the patio table, Cassie is told that she is in fact eating deer organs, so she runs into the RV with a mouthful of the food and it is all around her lips. As soon as she get to the bathroom to discover all of the skinned deers hanging inside, her mouth is suddenly empty and her lips are suddenly all clean, so that she can scream.Hamster
Corrected entry: When the family is sitting outside in the rain and decide to go to the bar, they go to the top of the mountain and begin sliding down feet first, one by one. However, they are seen at the bottom sliding head first.
Corrected entry: When the RV is stuck on top of the mountain, with all wheels off the ground, a close-up of the instrument panel is shown. The tachometer (RPMs) goes up as Robin Williams' character tries to free it, but the speedometer doesn't move at all. The speedometer would continue to function, as long as the RV was in gear, even if both rear wheels were spinning freely in the air.
